Title: Advertising support
Inventor: ROTH EDGAR
IPC: G09F11/00
Filed: 1990-06-09
Abstract: ABSTRACT     An advertising support comprises a housing (1) with lateral edges which are designed to link up with further supports and are each provided with two supply rolls (3) that turn in the same direction, and can be reversed.  The publicity material (7) is secured between two perforated adhesive viewing films (4) at a certain distance according to the width of the posters (7) to form insertion pockets of equal dimensions for receiving the posters (7). The web thus formed is then firmly bonded to a support film (8) facing the surface of the supply rolls (3).  Metallic coding marks (9) are provided directly on the poster (7) in such a manner that the distance between said coding marks (9) can easily be modified without damaging the adhesive viewing film (4).  The signals of the coding (g) are fed to the ROM memory of a CPU. They cause both driving engines (11) to switch over to slow motion through the CPU shortly before the image position is reached.  The viewing windows (12) are covered with one or several viewing films (13) which become transparent when a given voltage is applied and non-transparent when the voltage is switched off.  The distance between the poster (7) and the viewing film (4) is such that the contrast transmission from the surface of the poster is reduced.

IPC: F17C7/02
Filed: 1991-03-05
Abstract: A vapour eliminator and liquified gas dispensing system comprising a vessel (10) which is connected to receive liquified gas from a supply. The vessel (10) has a vapour discharge line (12) connected to the top (51) of the vessel so that vapour can be discharged. Sensing means (50) has a capacitive element (70) located in the top (51) of the vessel and which changes its capacitance in response to change in the phase of material in the vessel (10) to which the capacitive element (70) is exposed. The sensing means (50) generates phase signals in response to changes of the capacitance of the element (70) whereby the phase signals can be utilised to open or close the vapour discharge line (12) at the beginning or end of a vapour elimination operation respectively. The sensing circuit (65) may comprise an oscillator circuit (58) of which the capacitive element (70) is a component determining the frequency of the oscillator circuit, and a frequency responsive circuit (59) operative to produce an output signal in response to a predetermined change of the oscillator frequency. Alternatively, the sensing circuit (65) may comprise a bridge circuit supplied by an AC source, the capacitive element (70) being located in an arm of the bridge circuit whereby a change in reactance of the arm of the bridge within which the capacitive of element is located causes a change in the output of the bridge circuit thereby causing generation of the phase signal. Alternatively, the sensing circuit (65) may include a pulse generator (71), the characterisation of the pulse train depending on the capacitance of the element (70).

Title: Surface-treated medical devices
Inventor: BOSLEY RODNEY W
IPC: A61M/
Filed: 1993-04-20
Abstract: A dual lumen catheter is disclosed for providing extracorporeal treatment such as hemodialysis, which is percutaneously inserted for either short-term or long-term vascular access. The catheter includes a main body having proximal and distal segments connected to a pair of clamping limbs via a manifold. The distal segment includes two tubular members laterally attached to each other, one of which is thinner than the other and collapsible for inserting the catheter through a much smaller diameter peel-away sheath. contrary to existing practices, the lengths of the arterial and venous tubular members are reversed such as to provide a longer negative pressure intake lumen. A hydrophilic slip coating covers the distal segment to further ease the insertion of the distal segment into the peel-away sheath. The cross-sectional area of the proximal segment is generally elliptical shaped for providing a leak proof fit through the vascular access site. A ring-like grommet moveable along the proximal segment anchors the catheter to the surrounding tissue.      The lumens extending throughout the entire catheter are generally circular in nature and substantially equal in cross-sectional area to provide substantially equal flows of intake and return blood and to minimize clotting. The wall thickness of the negative pressure intake member is approximately one and a half to three times as thick as that of the thin-walled positive pressure tubular wall to maintain adequate flows of blood without collapsing or stretching.
